<P>PROBLEM TO BE SOLVED: To provide a multi-piece wiring board which reduces misalignment of a formation position of a dividing groove when the dividing groove is formed. <P>SOLUTION: A multi-piece wiring board manufacturing method comprises a step of forming a plurality of recesses 3 in a ceramic green sheet 1 by applying pressure on the heated ceramic green sheet 1 and forming a plurality of dividing grooves 6 by the ceramic green sheet 1 pushed aside and transferred when the recesses 3 are formed. Because each of the dividing grooves 6 is formed in a central region between the recesses 3, misalignment of the dividing groove 6 can be reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
